A High-Performance Cluster for Biomedical Research Using 10 Gigabit Ethernet iWARP Fabric
A large research institute has achieved performance of nearly 36 TeraFLOPS at greater than 84 percent efficiency using the HPL benchmark on a cluster of 4,032 cores. iWARP (Internet Wide Area RDMA Protocol) enabled these results using 10 gigabit Ethernet (10GbE) by reducing the overhead associated with kernel-to-user context switches, intermediate buffer copies, and TCP/IP processing.
EXECUTIVE SUMMARY
Using ubiquitous, standards-based Ethernet technology, iWARP enables low-latency network connectivity suitable for high-performance clusters. A key advantage of iWARP networking is its compatibility with existing network infrastructure, management solutions, and solution stacks.
This paper demonstrates the viability of cluster computing based on iWARP to achieve very high performance using 10GbE. It begins with a description of the architecture of a cluster based on iWARP connectivity before moving to a brief overview of iWARP technology. The paper concludes by reporting performance achieved using that cluster and observations about the value of iWARP to future work in this area.
Architecture of an iWARP Cluster for Medical Research
To support large-scale workloads in a range of areas critical to its research, including bioinformatics, image analysis, and sequencing, a research institution has built a large (4,032 cores) cluster using iWARP. For the compute nodes, they chose two-way Dell PowerEdge* R610 servers based on Intel® Xeon® processors x5550 running at 2.66 GHz with 24 GB RAM and a single 80 GB SATA hard drive in each server. For RDMA (remote direct memory access) network connectivity, the design uses NetEffect* 10GbE Server Cluster Adapters.
